Status of human task becomes "Reserved" when user claims a task but fails with "Unexpected error encountered"

Solution In Progress - Updated -


I have a human task in my jBPM process, when I login as a user into business-central and claim the task, there is some error happens and a pop-up message shows:

Unexpected error encountered:
**.**.**.Exception: ... ...

After that, the task status becomes Reserved, rather than the expected initial status Ready, why ?
